I don't know if i'm posting this in the right place? But I have a old Dell XPS Gen 2 running win XP home edition and found files and folders that say they were created on June 18, 2015. I checked my BIOS and everything is correct. I deleted these files and folders but next re-boot brings them back, not as many... but they grow every day. Virus scanner says "No viruses found" Computer runs fine.
